The leakage tracking tester is to apply a set voltage between the two electrodes on the surface of solid insulating materials and drop a specified concentration of liquid at a certain height to evaluate the leakage tracking resistance of the surface of solid insulating materials under the electric field and the polluted medium. It is suitable for lighting equipment, low-voltage electrical appliances, indoor electrical appliances, machine tool electrical appliances, insulation materials, engineering plastics, electrical connectors.
